Another solution to monitor if your computer is still in standby, is to use the Wake-on-LAN connector. Most modern ATX motherboards should have it. It’s a 3-pin connector near the PCI slots and will always give you +5volt. So all you have to do is hook up a led with resistor to the connector (mostly the powerled plug of your ATX case will fit on to it) and your standby led is ready!
